The front optical tamper detector will sense when the cabinet door has been opened. The rear optical tamper detector will sense when the cabinet is removed from its mounting surface.
Initialising the tampers should be the last thing you do before you leave the site.
If you will be completing the Installer Portal (configuration app) configuration on-site, initialise the tampers just before you activate the site.
If you will be leaving the site and completing the Installer Portal configuration off-site, initialise the tampers now.
When you have finished wiring the devices and no longer need to access the cabinet:
Close and lock the cabinet door using the key provided.
Within the SMB Installer Portal, open the site and click the Controller at the top of the hardware tree.
Within the Controller lightbox, select RESTART.
